A Colorado Senate committee on Tuesday advanced an ambitious paid family leave bill that was substantially amended by its sponsors in an attempt to alleviate the concerns of most of the state's major business chambers.

Colorado's Legislature gave final approval Wednesday to a bill that would dramatically change how the state regulates its multibillion-dollar oil and gas industry and sent it to Democratic Gov. Jared Polis, who is expected to sign it.

When Washington and Colorado launched their pioneering marijuana industries in the face of U.S. government prohibition, they imposed strict rules in hopes of keeping the U.S. Justice Department at bay. Five years later, federal authorities have stayed away, but the industry says it has been stifled by over-regulation.

Colorado's Democratic-controlled state government promised dramatic and sweeping changes Thursday in the way the state regulates oil and gas drilling, saying public health and safety would become the top priorities.

Colorado regulators have ordered a snap review of oil and gas pipelines after a fatal house explosion near a well, but they haven't said how they plan to fix a fundamental flaw in the system: They don't know where all those pipelines are.

Urged on by industry and business groups, a Republican-led Senate committee voted along party lines to defeat a proposal to extend the required distance between Colorado's schools and its oil and gas wells.
